'Unknown string' issue when backing up

SUGGESTED

Hi,

One of our clients has an issue where Sage 50 is displaying a message saying 'Unknown string' when running a backup - it seems to be when backing up the stkshort.report file

Error checking reports no problems.

Could this be a corrupted report file and we just need to remove / replace it to get the backup working?

Or is there a better way of fixing this?

Thanks

Ross
